Abstract

A fall protection device and its safety belt base. The fall protection device adapted to be connected to a safety belt includes a frame, a shaft, and a safety belt base, wherein the frame has a receiving place. The shaft is disposed on the frame. The safety belt base fits around the shaft and is located in the receiving place. The safety belt base includes a first portion and a second portion. The first portion has a ring, and the second portion has a sleeve and a reinforcement portion connected to the sleeve. The sleeve is surrounded by the ring and is adapted to be connected to the safety belt. The reinforcement portion is embedded in the ring. With the reinforcement portion, the structural strength of the safety belt base could be reinforced, and the first portion and the second portion could be prevented from disengaging from each other.

First claim

What is claimed is:

1. A fall protection device adapted to be connected to a safety belt; comprising:
a frame having a receiving place;
a shaft disposed on the frame;
a safety belt base which is fitted around the shaft and is located in the receiving place, including a first portion and a second portion, wherein the first portion has a ring, and the second portion has a reinforcement portion and a sleeve, which is surrounded by the ring and is adapted to be connected to the safety belt; the reinforcement portion is embedded within the ring; and
wherein the first portion has a first base plate, and a side of the first base plate is connected to the ring; the second portion has a second base plate embedded in the first portion, wherein a side of the second base plate is connected to the sleeve and the reinforcement portion.

2. The fall protection device as claimed in claim 1 , wherein the reinforcement portion comprises a plurality of pillars which are set at intervals and are embedded within the ring.

3. The fall protection device as claimed in claim 1 , wherein the first portion is made of a plastic material, and the second portion is made of a metal material.

4. A safety belt base which is adapted to be disposed in a fall protection device; comprising:
a first portion which has a ring adapted to be wound by a safety belt; and
a second portion having a sleeve and a reinforcement portion connected to the sleeve, wherein the sleeve is adapted to be connected to the safety belt and is surrounded by the ring, and the reinforcement portion is embedded within the ring; and
wherein the first portion has a first base plate, and a side of the first base plate is connected to the ring; the second portion has a second base plate embedded in the first portion, wherein a side of the second base plate is connected to the sleeve and the reinforcement portion.

5. The fall protection device as claimed in claim 4 , wherein the reinforcement portion comprises a plurality of pillars which are set at intervals and are embedded within the ring.

6. The fall protection device as claimed in claim 4 , wherein the first portion is made of plastic material, and the second portion is made of metal material.
